The issue is not when you have -march=native. The issue is when you use the default /etc/makepkg.conf file which contains "-march=x86-64 -mtune=generic" in AVX2 capable computers. Multi-core compilation is configured in your /etc/makepkg.conf as in any other package. For example, I have MAKEFLAGS="-j12".

what is the issue with: ###### CMAKE OPTIONS DISABLE BY DEFAULT ########### # If you are using a haswell CPU, you will have # # problems compiling with AVX2 support unless you # # modify march=native in the /etc/makepkg.conf: # # https://wiki.archlinux.org/index.php/Makepkg#Architecture.2C_compile_flagsAdd # ################################################### ? I compile on a haswell machine with -march=native and it produces a correct AVX2 executable. Are newer than haswell architectures also supposedly affected? And how about compiling on more then 1 core to speed up compile times?

NOTE: PROBLEMS BUILDING GROMACS AFTER GCC6 UPDATE WITH CUDA SUPPORT If your system has CUDA installed, gromacs installer by default will try to compile with CUDA support. Unfortunately, currently gcc6 and CUDA do not play well along and the compilation will fail. Because of this the later cuda release comes along with gcc5 package. Using gcc5 we can again build gromacs in bash using the following commands: export CC=gcc-5 export CXX=g++-5 makepkg

Sorry, I'm not sure I'm understand really your problem. This package is the default gromacs and as such is installed in: /usr/bin /usr/include /usr/lib /usr/share I just build the package and it works perfectly with the files installed in above directories. Are you sure that you are installing gromacs and not aur/gromacs-5.0-complete or aur/gromacs-4.6-complete which indeed install this version of gromacs in /usr/local. In this latter packages the intention is that they can coexist with the last stable version in case your projects still require them and because of that they are encapsulated in /usr/local/gromacs-XXX/ If your problems persist please provide more details.

Thanks for the PKGBUILD! There's one odd thing though. Am I the only one whose installation prefix specification is totally ignored by Cmake? In build() cmake is run with -DCMAKE_INSTALL_PREFIX=/usr/. But that is totally ignored, as is revealed during package(): gromacs was still installed into ${pkgdir}/usr/local/gromacs, not ${pkgdir}/usr, so I had to replace all instances of /usr with /usr/local/gromacs.

1) Now tests are run by default. If you do not want them comment out the "make check" lines. 2) License has been corrected to LGPL 3) Specific SIMD is not longer enforced. Gromacs will detect the best for your system. If you have any problem with this modify march=native in the /etc/makepkg.conf 4) I have cleaned the PKGBUILD and some options which are default 5) I will like to keep both double and single compilation together as many times double are also required especially for minimizing. In the future we might consider a separated split package. 6) I want to minimize the usage of AUR-libraries, that's why I won't make default fftw-bettersimd. You can also make another package, Eg. gromacs-fftw-bettersimd, to incorporate your changes if you want to.

FYI any who are trying to enable tests replace "make test" with "make check".

<deleted-account> commented on 2015-07-14 20:07 (UTC)

Thanks for the response. Concerning the test, don't comment out "make test", because that is not the correct command. Just replace it with "make check".
